The VENOM LR is a rotary autocannon derived from the ADEN 30 mm gun, although most of its components and working principle are different.
It is designed to be fired from remote controlled weapon stations (RCWS) that can mount 12.7 mm machineguns.
[1] The VENOM LR is designed for RCWS integration where reduced recoil forces permit installation onto light reconnaissance vehicles and fast patrol vessels.
The guns' recoil mitigation system is based on the same principles as applied to the aircraft mounted ADEN cannon.
The company claimed that it is up to 50% cheaper than the Orbital ATK M230LF, thus making it a highly competitively priced, and non-ITAR (International Traffic in Arms Regulations), alternative to the M230.
